Short answer: you are SOL. If the camera didn't capture the pixels in that area due to either over or under exposure, no amount of processing will get them.Rockslinger said:FLASH photography. Why are so many pics using flash overexposed or underexposed? Isn't the camera smart enough to judge the right amount of flash needed to get a good pic every time?
Which is easier to correct afterwards? Overexposure (too much flash) or underexposure (too little flash)?
If you are only a little over or under exposed, then you can adjust, and it doesn't really matter which way.
As to the camera figuring it out, it did, but only for the part of the picture it was light metering. If the rest of the picture is different, due to distance or ambient lighting, the camera's not smart enough to figure that out. Most will use matrix metering, meaning the central part of your frame, so if you are using the 1/3 and not centering your subject, focus and exposure can be off.
First thing I do is turn matrixing off for both focusing and exposure, limiting it to the pinpoint center, then I'll focus on subject, shift the camera to the composition I want and then shoot. Works better for me, that way I'm choosing what data the camera uses, rather than a matrix.
Any pro's jump on here...
